Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
PM / devfreq: Check governor before using governor->name<br />
<br />
Commit 96ffcdf239de ("PM / devfreq: Remove redundant governor_name from<br />
struct devfreq") removes governor_name and uses governor->name to replace<br />
it. But devfreq->governor may be NULL and directly using<br />
devfreq->governor->name may cause null pointer exception. Move the check of<br />
governor to before using governor->name.
